“Lightroom on the web makes it possible for you to access all of your Lightroom images from nearly any computer around the world, and today we’re announcing the addition of Technology Previews, a series of features that will let you test drive new functionality before it’s officially available. The first Technology Preview we’re making available is Search, which coupled with our new image analysis technology, lets you search through any image you have synchronized online, either with Lightroom for mobile, Lightroom on the web, or with Lightroom desktop through a synchronized collection. We’ll be releasing new Technology Previews as they’re ready, which you’ll be able to use and even provide feedback on the functionality, helping to shape the feature.” —Josh Haftel, The Lightroom Journal
To enable the feature launch Lightroom on the web (https://lightroom.adobe.com), and log in. In the upper left, click the LR menu, then click to select Technology Previews from the list.
Toggle on the Search switch and choose Apply Changes.
The search technology will search on a lot of different things, including metadata such as file names, captions, titles, camera, lens, and exposure data, location, faces, etc. It will grow to include additional data in the future (hence the “technology preview”). You can also try searching your library for general topics such as food, travel, animals, and more.
Note: it might take a little bit to create the initial index of your photos (depending on how many you are working with) in order to return the optimal search results.
